Do you use lane departure warning/assist feature?

I used it when I was tired and had to drive. Luckily I upgraded the system with comma.ai openpilot. It makes it stay in it's lane almost perfectly. It was an expensive but worthwhile addition. The stock thing was only good enough to keep me awake everytime I hit the lines.

 

I use it all the time except when it's raining heavily (i'd rather not have some other entity want to move the when on me when the driving conditions are poor). I find it quite useful for it's intended purpose (to let me know if i'm drifting).

I actually HAVE fallen asleep at the wheel (when I was 20 driving across country). The rumble strip saved my life. I view this as a rumble strip. The road may not always have them, but if it does it's a good thing.

as far as adaptive cruise control, I absolutely love it. I've had it since my gen 3 and will never again buy a car without it. When I was commuting daily into the NYC financial district I would sit in huge traffic jams. The car would accelerate and decelerate automatically. A tiny tickle of the cruise stalk was all it took to re-engage after coming to a full stop. It made sitting in traffic much more palatable.

 

I agree 100%. With very very rare exceptions, I never turn any safety feature off. And I love the adaptive cruise control!

 

I have just finished an arbitration against Toyota regarding the Lane Departure Warning w/Steering Assist. The Steering Assist admittedly does not work the same as on other Toyota models but they refuse to fix it and claim the Prius works like all other Prius do but they do not work like every other Toyota model. All Toyota advertising and marketing material tout the Safety Suite to be the same on all Toyota models. I am assembling a group of Prius owners to be part of a class action suit. No money will be required nor will anyone have to do anything beyond agree to be part of the class. Please reply to this post if you have an interest for more information.

 

Just bought a 2019 Prius Prime. The Lane Departure Alert system on this car just beeps if you approach the lane lines; the Steering Assist feature gives slight, barely perceptible nudges to the steering. It can't prevent you from drifting completely over the lane line even on a straight road, let alone on a curve, so for all practical purposes, it's basically useless. My fiance just bought a 2020 Corolla Hybrid, and the Steering Assist function is much more functional - on the Corolla, it actually steers the car along freeway curves, and as long as the lane striping is clear and fresh, it can keep the car centered in the lane far more accurately than I can myself. Very disappointed, and at first I thought I had a defective car, but it looks like all the 2019 Primes have this issue.
The radar-assist Adaptive Cruise Control works very well, and I'm very pleased with this feature.

 

You have correctly defined why I had no problem with trading in our Prius Prime for a Model 3.

I turned this off, along with the dynamic cruise control. Both very poorly implemented on the Prime, in my opinion.

 

TSS 2.0 with LTA is the feature that everyone wants (not available with Prime yet).

LDA is just a sensor to remind you to signal changes as Bob stated or to wake you up if you are falling asleep (if the road still have the unfaded lines)

 

I'm not in that "everyone" group. I don't want this.

 

My Boss drives a Panamera and I asked him what type of Safety Feature it has.. and he said does not care as he drives and control the way he wanted it. Pretty much like you. I am with you to self control the car and turn off all the auto features that we all did in our era but for (no offense to anyone).. new kids, some ladies or elderly people, those safety features are a bonus

 

We're talking here about Prius - a primarily commuter vehicle. The safer it can get my body from A to B, the better. For fun/driving experience/midlife crisis/etc. there're plenty of other options.

P.S. I assume that class action suit never happened?

 

I just went on another trip that had two legs a Model3 LR couldn't do, much less a base model. The Prime did them both with over 250 miles of range to spare.

The LDA/SA works as described in the manual and on the Toyota video. If you want lane trace instead, that's not available on the Prime nor was it ever advertised to have it. Yeah, I'd probably like it but there's no way in hell I'd pay double or triple for a car that has 1/2 or 1/3 the range just to get road following and acceleration rates I'd have to find a way to disable.

 

If I believed any of the current driver "aids" in my Prime made me safer, I'd use them. But, they don't work well, so they stay turned off so as not to distract me from driving the car safely.

 

LDA/SA is absolutely a useful safety approach. It can wake you up if you fall asleep and it can keep you on the road longer if you are asleep.

What stinks is BSM doesn't beep, making it entirely useless. And that's a really big one.

 

Safer yet, don't even start driving when you are tired. And, when you are tired, pull over to rest. Don't count on some feature of the car to protect you (and those of us sharing the road with you) from yourself.

 

Often times, reality strikes.

On my last trip, I pulled over twice to let my wife drive because I wasn't up to it. But sometimes I'm alone, sometimes I have to be somewhere, sometimes the family is asleep, and I pretty much have to drive.

Saying don't drive if you're tired is like saying don't do anything cancer-causing. Sometimes you're going to be outside in the sun and there's nothing you can do about it.

 

To borrow your words I agree.
IDK if LDA can be disable but I do not like that at all

 

You pretty much don't have to drive if you are tired. It's a choice you make. Pull over, drink some caffeine, do some jumping jacks. Just don't put the rest of the road at risk because you "have to be somewhere."

 

I changed the sensitivity and it usually stares my car back into the lane. I found it at first it really didn't work until I change the sensitivity on it. I wish the newer Prius Prime come with the newer 2.0 version of it but it doesn't. It works fine for me.

Caffeine will disable me, and exercise doesn't really work.

The alternative is often putting someone else at risk.
